以上是错误信息。 下面是无法编译文件的程序

错误在哪里，为啥不能编译·····

一种方法就是不断一小段代码
去都某一段 错误消失了
接下来 你懂的

Nani? What do you mean~ There is nothing wrong no matter how you look at it, why can’t it be compiled? It shouldn't be an environmental problem. Other jsp files run normally, but this one doesn't. . .

Found it out, it’s the reason for this sentence<%@page import="javax.enterprise.inject.New"%>. The auto-prompt function caused this class to be imported accidentally. . . But why is the error reported? I haven’t used it. Check it out~~~~It hurts

One way is to continue a small piece of code
and go to a certain section The error disappeared
Next thing you know

Haha, this is my way to troubleshoot js errors, because I write a lot of js, and there are smart prompts Poor, so I chose the method of constantly removing code segments. Locate where the error is
Once you find the error, it will be solved~
I am doing .net and I am not familiar with Java
But if you locate the error, it should be easy to solve
